CALICU-PRINTING MACHINE.

Specification of Letters Patent.

Patented May 23, 1922.

Application filed December 16, 1920. Serial No. 431,164.

To all whom it may concern Be 1t known'that I, THoMAs HINDLE, a

British subject, residing at Glossop, county of Derbyshire, England, have invented certain new and useful Improvements in Calico-Printing Machines, of which the following is a specification.

This invention relates to calico printing machines and is designed to provide for the printing of two patterns at the same time from two or more sets of printing rollers of diflerent sizes or of which the circumference of one is greater than that of the other, while each set of printing rollers is maintained in register. Patterns can also be printed and padded or covered with one or more colours at the same time.

It consists in the particular disposition of the printing rollers and gear wheels by which they and the main cylinder are driven comprising a plurality of sets of printing rollers each set of a different diameter, a crown or pinion wheel on the driving shaft, box wheels gearing therewith on the man drels of one set of printing rollers, which drive the main cylinder by frictional contact therewith, box wheels at the opposite side of the machine on the mandrels of the second set of printing rollers of different size from the first set driven by f ictional contact with the main cylinder, and a free wheel on the cylinder shaft in gear with both box wheels on the second set of printing rollers to ensure the rollers of this set running exactly together and keep the pattern thereon in fit.

The invention will be fully described with reference to the accompanying drawings Fig. 1 is a diagrammatic front elevation of printing machine.

Fig. 2 is a plan of same.

Fig. 3 is an end view of cylinder and rollers.

Fig. 4 is a section of same.

The main cylinder A is mounted in the frame B in the ordinary manner. Two or more front printing rollers C are mounted in the ordinary way at the front of the machine and two or more back printing rollers D are mounted at the back of the machine, the rollers C and D being in frictional contact with the cylinder A.

The back printing rollers D are of greater or less diameter than the front printing rollers C.

A crown or pinion wheel E is fitted to the driving shaft 6 which is mounted in the usual way in bearings independently of the cylinder A and a box wheel F is fitted on the mandrel of each of the front printing rollers, C. The crown wheel E gears with the box wheels F and drives the latter and the rollers C, and the rollers C being in frictional contact with the cylinder A, drive it.

At the other side of the machine a free wheel or pinion G is mounted to rotate in dependently of the cylinder and a box wheel H is fitted on the mandrel of each of the back printing rollers D. The free pinion G gears with the box wheels H, and the back printing rollers D being in frictional contact with the cylinder A are driven thereby and drive the loose wheel Gr, its function being to keep the back rollers D running exactly together to maintain the pattern thereon in register or fit.

It will be obvious that the driving may be reversed by driving the back printing roll ers D from the pinion E on the driving shaft and the cylinder A by them and driving the front printing rollers C by friction from the cylinder A, box wheels on their mandrels gearing with the free wheel Gr.

By this construction it is possible to print at the same time two patterns and keep in register the set of rollers comprising each pattern when the set of rollers for one pattern are of different size or different in circumference than those of the other pattern. Also styles which usually require to be run twice or more through the machine may be printed at the same time or by one op eration thus making for increased production. Thus two colour patterns, such as acid and red or other suitable colours may be printed and padded at the same time, the same with patterns for covering with one or more colours.

V here only one roller is required after a two colour pattern a plain or a starch roller may be used, the same size as the one roller, the pull being then equal to the drag of the cylinder.

What I claim as my invention and desireto protect by Letters Patent is In a calico printing machine the combination with the main cylinder and a set of printing rollers in contact therewith set of printing rollers in register substantially as described. 7

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
